Measurement Systems & Controls - DM6400 Dynamic RAM
The DM and DMB series of boards were quite similar. The DM did not have bank
select capability, the DMB did.
The board consisted of 64K of dynamic RAM with refreshing independent of bus
timing. No wait states were required wit a 4MHZ Z80. The board was
addressable in 4K increments at 4K boundaries. The board utilized low
power, fully loaded it used less than 8 watts.
I do not have a manual for this board. If you can provide a copy or pdf file
please let me know.
